Question

For constructive interference to take place between two monochromtic light waves of wavelength A, the path difference should be, *

Answer 1

For constructive interference to take place between two monochromatic light waves of wavelength λ, the path difference should be (c) nλ. ... When a greater resultant wave is formed, it is called constructive interference and when a resultant wave of lower amplitude is formed, it is destructive interference.
